东亚区域云掩膜及云相态数据集（2016-2024）

本数据集为基于Himawari-8（葵花-8）静止气象卫星开发的云掩膜产品，空间覆盖范围为东亚区域（80°E-200°E，60°S-60°N），空间分辨率为0.05°（约5 km），时间分辨率为逐小时。数据内容包含云区二值标识，其中像元值1表示云覆盖，0表示无云区域，可为气象预报、太阳辐射资源评估及大气模型提供基础输入。数据源自Himawari-8卫星多光谱通道观测，通过标准化遥感反演流程生成，数据生产过程中已进行辐射定标和几何校正。

This dataset is a cloud mask product developed based on the Himawari-8 geostationary meteorological satellite (known as Kuihua-8 in Chinese). Its spatial coverage encompasses the East Asian region (80°E–200°E, 60°S–60°N), with a spatial resolution of 0.05° (approximately 5 km) and an hourly temporal resolution. The dataset includes binary cloud masks, where a pixel value of 1 indicates cloud cover, and 0 represents cloud-free areas. It can provide fundamental inputs for weather forecasting, solar radiation resource assessment, and atmospheric modeling. The data originates from multi-spectral channel observations aboard the Himawari-8 satellite, and is generated through standardized remote sensing inversion processes. Radiometric calibration and geometric correction have been performed during the data production stage.
